Don't go for a dip in the hot tub.

According to Dr. Elcy John, an OB/GYN at Memorial Hermann Medical Group, the American College of Obstetricians and Gynecologists (ACOG), advises pregnant women to not let their core body temperature rise above 102.2 degrees Fahrenheit.

Sitting in a hot tub could raise the body temperature too high and harm the developing baby.
